Recreating the Animation Nodes FCurve Animation Offset Template
Lets say we have a cube with some f-curves that controls its location.



And we have an array of spheres that we want to transform based on the f-curves of the cube with an offset it time.



What we are going to do is create a loop that evaluates the x, y and z f-curves at multiple offset values, combine the result in a vector and append it. The offsets shall be of uniform range generated using the Float Range node.



By adding the evaluated locations to the locations of the spheres, we get the result you are looking for.
